SEGMENTED GRINDING WHEEL AND METHOD OF MANUFACTURING SAME

摘要

It is intended that the expansion and contraction of a disc-like core do not impose a compression stress or the like on adhesives situated between adjoining segmented chips. A plurality of segmented chips 11 are reinforced by applying an adhesive 20 to the circumferentially opposite end portions thereof, and the adjoining segmented chips adjoining in the circumferential direction are adhered to the circumferential surface 21a of a disc-like core 21 with the adhesives at the circumferentially opposite end portions being not jointed with each other. Thus, the segmented chips can be prevented from being loaded with an unnatural force even when the disc-like core with the segmented chips adhered thereto expands and contracts radially due to thermal expansion and thermal contract.
